Description générale
Trehalase is a glycosidase that occurs in many forms and is found in all tissues. It belongs to the glycoside hydrolase 37 (GH37) family of the carbohydrate-active enzyme (CAZy) classification.
Trehalose is the main haemolymph sugar in most insects and is potentially a prime target for an invading pathogenic fungus.
Application
Trehalase has been used:
- in a study to assess changes in carbohydrate metabolism in Plasmopara viticola-infected grapevine leaves
- in a study to investigate growth arrest by trehalose-6-phosphate
- to quantify the intracellular trehalose in Lactobacillus casei cells
Actions biochimiques/physiologiques
Trehalase catalyzes the hydrolysis of trehalose to produce two glucose units. It mediates flight metabolism, molting induced chitin production and tolerance towards cold temperature.
Définition de l'unité
One unit will convert 1.0 μmole of trehalose to 2.0 μmoles of glucose per min at pH 5.7 at 37 °C (liberated glucose determined at pH 7.5).
Forme physique
Solution in 50% glycerol containing 1% Triton™ X-100 and 25 mM potassium phosphate, pH 6.5

Although trehalose has recently gained interest because of its pharmaceutical potential, its clinical use is hampered due to its low bioavailability. Hence, hydrolysis-resistant trehalose analogues retaining biological activity could be of interest. In this study, 34 4- and 6-O-substituted trehalose

Although intraspecific variation in metabolic rate is associated with variation in body size, similarly sized individuals nonetheless vary greatly. At similar masses, hovering bumblebee workers (Bombus impatiens) can differ in metabolic rate up to twofold. We examined how such interindividual
